Extending the network’s edge far beyond what was possible

C-LAN Micro cellular network topology provides M2M, Bi-directional IP access to low power, short range, battery operated devices/ sensors. C-LAN does not require any ambient RF Infrastructure (WiFi, large scale cellular) operates outside of IT Domain. C-LAN requires a single IP interface (Ethernet/cellular modem) regardless of C-LAN coverage area. C-LAN can be installed into existing structures with no retro-fit, available AC power is the only requirement. Battery/solar power can be used for temporary, Ad-Hoc network capability if no AC available. This would indicate C-LAN could be used in emergency/field application
